# zrepair.ps1 — audit and repair container/proxy routing on the server, then smoke test.
#
# Usage:
#   zrepair <project> [<project> ...]
#
# For each project: shows compose status, starts the stack if it's down,
# validates the edge proxy's nginx config (once, if an edge project is defined),
# and smoke-tests the live domain.
